From March 16 to 21, 2025, the Spring Meeting of the Condensed Matter Section (SKM) of the German Physical Society (DPG) took place in Regensburg. With more than 6,000 participants, it is Germany’s largest physics conference and an important platform for researchers and industry representatives from all fields of physics and technology. Dr. Christof Eigner and Dr. Michael Rüsing from the Paderborn Institute for Photonic Quantum Systems (PhoQS)…
Am 11.3.2025 fand das jährliche Projekttreffen des BMBF-Projektes „Heranführung der Generation Z an die Denkweise in der Quantenphysik – HedwiQ“ statt. Diesmal war der Treffpunkt kein Seminarraum an der Uni, sondern das CoolMint Schülerlabor am Heinz Nixdorf MuseumsForum, denn es gab etwas zu feiern. Die ersten Labormodule, die seit dem Projektstart im Oktober 2023 erdacht, entwickelt und realisiert worden waren, sind in ihren finalen…
On the 27th of March, the Optica Student Chapter of Paderborn organized a half-day workshop on scientific writing and publishing held by Dr. Claus Roll, Senior Deputy Director of Optica. The event focused on the preparation for writing a scientific article, its structure, journal selection, as well as the ethical issues governing experiments and the publishing process.
Special thanks to Optica and PhoQS for financial support!
Image (Paderborn University, M. Hammer et al.): In this publication, two different types of TFLN slab waveguides are considered, which differ in their optical properties due to their manufacturing processes ((a) ‘X-cut’ or b) ‘Z-cut’ configuration).
Thin-film-lithium-niobate (TFLN) is a highly relevant material in integrated photonics due to its high efficiency and bandwidth. It offers enormous potential in the miniaturisation of components, making it essential for future quantum technologies.
To gain a deeper understanding of the optical properties of thin-film-lithium-niobate, Manfred Hammer et al. have analysed the propagation of light in dielectric slab waveguides made of TFLN, operated…
Since 2008, the Emil Wolf Outstanding Student Paper Competition honours young researchers for outstanding presentations during the Frontiers in Optics + Laser Science (FiO+LS) conference. A prize of USD 300 is awarded in each of seven different categories.
PhoQS represented at Frontiers in Optics + Laser Science
Several researchers from PhoQS took part in this year's FiO+LS, which was held in Denver, Colorado, at the end of October. Federico…

The Wyant College of Optical Sciences (OSC) at the University of Arizona is one of the most renowned educational and research institutions in the field of optics and photonics. Among other things, it hosts the “Arizona Quantum Initiative”, and the NSF-ERC funded “Center for Quantum Networks”. Stefan Schumacher, research group leader at PhoQS, is adjunct professor of optical sciences at the University of Arizona – currently, he is spending his…

Publication in ‘Quantum Science and Technology’
Scientists at Paderborn University have used high-performance computing (HPC) for the first time to analyse a quantum photonics experiment on a large scale. Specifically, this involved the tomographic reconstruction of experimental data from a quantum detector. This is a device that measures individual photons, i.e. particles of light. Among other things, the researchers developed new HPC software…
Quantum Photonics Spotlight 2024 [QPS2024], organised by the Institute for Photonic Quantum Systems (PhoQS) of Paderborn University, took place at the Heinz Nixdorf MuseumsForum from 8 to 10 October 2024. With a total of 65 invited speakers and 84 poster presentations from all over the world, a scientific programme of the highest quality was created. A total of 260 participants spent the three conference days in Paderborn – and are looking…
